Title 54 › Subtitle I — National Park System › CHAPTER 1015 — TRANSPORTATION › SUBCHAPTER II — ROADS AND TRAILS › § 101511
The Secretary may build, rebuild, and improve roads and trails (including bridges) inside System units. The Secretary can also name certain roads as "approach roads" when they mainly serve travel to a System unit, run across land at least 90 percent federally owned, and link a System unit to a nearby point on or leading to the National Highway System. A designated approach road must be no longer than 60 miles to the nearest convenient National Highway System road, or 30 miles if the approach road is itself on the National Highway System, and no more than 40 miles of any one approach road may be in a single county. Approach roads count as part of the unit’s highway system. The Secretary may build or fix these roads, make maintenance deals with states or counties, and spend up to $1,500,000 per year on their construction and improvement. If an approach road crosses a national forest, the Secretary must get the Secretary of Agriculture’s approval before starting. The Secretary of Transportation may do these tasks under an agreement.
